The MM-PSF is an embedded isolated power supply by MicroMax Computer Intelligence, designed specifically for РС/104 systems.
It provides a РС/104 system with 12V DC (5A max.), 5V DC (12A max.), 3.3V DC (2.5A or 7A max.), −12V DC (2A max.) output voltages. The combined power of the device is up to 60W.
The power supply features reverse polarity protection and transient voltage surge suppression. The MM-PSF has advanced electromagnetic compatibility (MIL-STD-461F compliant).
The output power is supplied to latching connectors, as well as to system buses PCI-104 and PC/104. The device features short circuit protection with no time limit. As soon as the connection is recovered, the MM-PSF restores power supply automatically.
The MM-PSF is designed in compliance with vehicle standards MIL-STD-1275D and MIL-STD-704F.
